ABSTRACT Electronic perturbation of the surfaces Cu catalysts is crucial for optimizing electrochemical CO2 reduction activity, yet still poses great challenges. Herein, nanostructured nanowires (NW) with fine-tuned surface electronic structure are achieved via encapsulation electron-withdrawing (–F) and -donating (–Me) group-functionalized graphdiynes (R-GDY, R = –F –Me) resulting catalysts, denoted as R-GDY/Cu NW, display distinct performances. In situ spectroscopy revealed that *CO (a key...
We report herein a series of Cp*Ir complexes containing rigid 8-aminoquinolinesulfonamide moiety as highly efficient catalysts for the dehydrogenation formic acid (FA). The complex [Cp*Ir(L)Cl] (HL = N-(quinolin-8-yl)benzenesulfonamide) displayed high turnover frequency (TOF) 2.97 × 104 h–1 and good stability (>100 h) at 60 °C. Comparative studies with ligand [Cp*Ir(L′)Cl] (HL′ N-propylpypridine-2-sulfonamide) without aminoquinoline demonstrated that 8-aminoquinoline could dramatically...
Pyridyl-containing graphdiyne provides well-defined sites for stabilizing sub-2 nm copper nanoclusters, which show an optimum CH 4 faradaic efficiency of 58% in the electrochemical CO 2 reduction reaction.
Abstract Surface functionalization of carbon materials is interest in many research fields, such as electrocatalysis, interfacial engineering, and supercapacitors. As an emerging material, γ‐graphyne has attracted broad attention. Herein, we report that the surface a γ‐graphyne‐like material ( γ‐G1 ) achieved by immobilizing functional groups via click chemistry. Texture analysis aberration‐corrected microscopy, X‐ray photoelectron spectroscopy, electrochemistry confirm successful...
Abstract Metal sub-nanoclusters (SNCs) inherit the metrics of unsaturated active sites and ultrahigh metal utilization from single-atom catalysts (SACs), they can drive reactions involving multiple adsorbates by their enriched cofactors that beyond SACs. However, current synthetic strategy offers limited versatility to prepare SNCs due subnanometric feature high surface. Herein, we demonstrate a universal facile one-pot reaction construct wide assortments with size 2 3 nm on graphdiyne...
